IEX Extends Trade Data Timestamp Exemption to 2030
Published Date: 6/25/2025
Notice
Summary
Investors Exchange (IEX) is updating a rule to extend a special permission about how precise trade timestamps need to be, pushing the deadline from 2025 to 2030. This change affects traders and firms using the Consolidated Audit Trail system and helps keep reporting rules clear and consistent. The update is effective immediately and won’t cost anyone extra but makes compliance easier for years to come.
Analyzed Economic Effects
2 provisions identified: 2 benefits, 0 costs, 0 mixed.
CAT Timestamp Exemption Extended to 2030
If you are an Industry Member that captures timestamps finer than nanoseconds, IEX amended Rule 11.660 to keep the requirement that such timestamps be truncated (not rounded) after the nanosecond level for submission to the Consolidated Audit Trail (CAT) until April 8, 2030.
Amendment Became Operative Immediately
The Exchange filed the proposed rule change on June 17, 2025 and the Commission designated it operative upon filing, so the amended Rule 11.660 reflecting the extended exemption is effective immediately upon filing.
